Mad Professor Mariarti is a platform game with elements of logical games and puzzles. Available since 1990 and published by Krisalis Software Ltd. As the name of the game suggests, we are dealing here with the action of the mad professor Mariarti. Some of his experiments have failed. Due to the professor's bad decisions, there was a lot of chaos in five of his laboratories. Some lab items and equipment have come to life, so Mariarti must do everything possible to close these five laboratories and prevent chaos from spreading. The player not only directs the character in such a way that it jumps over the gaps, as in a typical platformer, but also has to protect the professor from opponents. At the beginning you have to defend yourself with what you will find in the laboratory, but the coins collected during the game will allow you to buy more advanced weapons, e.g. a laser cannon. In addition, there are a few puzzles and puzzles to solve, all in order to get to the end of the level and finally press the switch.
